Make ioctl wrappers for functions that will be used by the in-kernel API.
The following functions are touched:
- drm_mode_create_dumb_ioctl()
- drm_mode_destroy_dumb_ioctl()
- drm_mode_addfb2()
- drm_mode_rmfb()
- drm_prime_handle_to_fd_ioctl()
drm_mode_addfb2() also gets the ability to override the debug name.
